                  • Motivational factor for being available during peak hours
                  In order to attract and retain adequate resources for reliable operation of
                 the energy market, revenues from energy, ancillary services and  capacity
                 must be adequate to cover the overall cost of power plants. The capacity
                 payment plays vital role of assuring the revenue  sufficiency of the suppliers
                 as well as reducing the magnitude of  inappropriate price volatility.

                 Transmission Service

                 Regional Electricity Companies (REC) are the transmission owners and
                 paid for the transmission services they provide. Payment for transmission
                 services is based on capacity and energy flow. Transmission lines and
                 power transformers  are subject to payment based on  their available
                 capacity and also the energy passing through them. Total transmission
                 costs are allocated to all buyers and sellers to remunerate RECs.

                 Buyer’s Bill

                 It  is  worth  mentioning  that  beside  their  role  in  transmission  services,
                 Regional Electricity Companies (REC) act as the suppliers for high  voltage
                 consumers.  Hence, in  spot market, RECs  and  electricity    distribution
                 companies  (EDC)  are the registered buyers  in  the spot market. The
                 buyers that purchase energy from spot market will pay hourly market
                 average  price.
